PRESS-BOX.

United States of America, and residents of the city, county, and State of New York,

have invented certain new and useful rm rovements in Press-Boxes, of which the folowing is a specification.

Our invention consists in a new and useful improvement press-boxes for use with oilpresses employed for the purpose of expressing cotton-seed and-similar vegetable oils.

" The object of the invention is to enable the box to be cast from steel in one piece instead ess satisfactory process of riveting'a'nd bolting or otherwise fastening together an assems blage of various elements; and a'further object is to enable the entire boxto occupy a minimum amount of space and to provide a maximum opening between the boxes for reof being built up by the more expensive and I ceiving the cakes.

The invention consists, essentially, in the construction, arrangement, and combination of parts, substantially as will behereinafter described and then more specifically pointed out in the clauses of claim; x

In the accompanying drawings, Figure 1 is a view in elevation of a press composed, of a lural-arrangement of our improved pressoxes. Fig. 2 is a top plan view of one of the boxes. Fig. -3 is aside view of the same. Fig. 4is a transverse view offour boxes, the upper one being shown in end elevation, the onebelow it in section on theline 00 m of Fig.

On the other hand, built-u boxes, as we term them, being compose of a plurality of'parts fastened together, have a tendency to come apart at the joints, especially the joints of slde walls. gle piece from cast-steel or similar material,

we gain many benefits and provide a box which is extremely usefuland which does its work with remarkable facility. I

1 designates the main part. of the box, which is square or rectangularform, and of such substantial thickness as is suited to give it strength and enable it to perform its work. It is provided with a grating 2, consisting of parallel grooves formed in the up er face of part 1. In the old style of boxes t 's grating 2 is commonly removable.

box, although it may be made as a removable part, if desired.

On the grating 2 rests the mat 3, Whichis perforated, and onmat 3 the cake rests.

The main part 1 is provided laterally on its two longer-sides with the outreaching flanges below the thickness of'the part 1 said reduced sections 4 being made integral with the main box 1 and being drilled at 9 for the bolts 11, which We preferto cast,

a steel plate or block, preferably of keep the boxes in positionrelatively to each other, said lateral sections being provided at their middle-points with notches 15, which loosely engage. the upright rails 22 of the frame of the press. (Indicated in Fig.

with the flanges 5, whose inner opposing faces as indicated in the showing of the top box in Fig. 4. At the extremities of the flanges 5 are the lips or guides 6. larger portion is cut away at 8, leaving only a short portion (See Fig. 3.) The distance between the inner faces or flanges 5is slightly more than the width of T of the material of the flanges 5 the top grooved face of the main box 1, and

between these faces the mat 3 of the lower box is. received and makes a fairly tight fit. The lower box with its mat reciprocates up and down in this space between flanges 5'5 for the purpose of compressing the cake betweenlthe mat 3 and the bottom of the box -1.

ICQ

The flanges 5 are integral with the box 1.

Furthermore, at the ends of the reduced lateral sections 4, alongside the vertical faces 16 on the sides of box 1 and above the guides 6, formed on flanges 5, are corner seats or surfaces 7', as indicated in Fig. 5, which are flat and smooth and are depressed below the surfaces of the sections 4, and in these depressions or recesses, above the surfaces 7, ceived at timesthe guides 6 of the box aboveas, for instance, when two boxes like the two lower ones in Fig. 4 are telescoping with each are reother with no cake between them to be pressed. The exact shape, however, and form of these corner-surfaces 7, of which,

obviously, each box has four, may vary withy in wide limits and must correspond to the general shape and structure of the box.

It is important in an oil-press of this type that the mat should fit closely between the parts 5 5 ofthe box and should be retained there during its movements, never being allowed to drop below the bottom ends of the guides 6that is to say, it should always be embraced by the depending flanges 5 at the sides of the box, for if it should be otherwise it might swing sidewise to a small amount when it drops down near the lower ends of the guides 6, which would cause it to slip underneath the guides 6, andthis would cause damage when the box below carrying said mat was again lifted. The lips or guides 6, one at each corner of the box, hold the boxes telescoped when opened to their full width, as indicated in the showing of the top box and the one immediately below it in Fig. 4, and these lips or guides 6 allow a wider opening than would otherwise be possible.

We do not limit ourselves to making this box of cast metal. The same result in the matter of telescoping may be attained in a built-up box by planing or milling away the end portions of the reduced sections 4 to provide the depressed corners 7, which will receive the guides 6 in such a way that said guides will not strike the surfaces 7 when the boxes are closed together in the manner shown in Fig. 4:, the two lower boxes without any cake between.

As our invention relates to a press-box forming one member of a series of boxes employed in an oil-press of the multiple-box type, we have indicated in Fig. 1 the general form of such a press consisting of the cornercolumns 21 and the head-tree 20, connecting the columns 21. Within the columns is a series of boxes 1, as many in number as is desired, which are operated by hydraulic or other pressure to compress the cake between them and express the oil.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a press-box for an oil-press of the multiple-box type, a main part having longitudinal lateral sections of less thickness, said sections having downwardly-projecting guides near the ends, and having also on their upper surfaces thinned-out portions near the ends, so that two boxes may telescope and the guides on the one enter the recesses above the thinned-out portions on the other.

2. In a pressbox for oil-presses of the multiple type, a main portion having a grating and designed to carry the mat and having its longitudinal sides practically parallel, said sides having lateral sections of reduced thickness, which sections have corner depressions above and corner-guides below, all arranged to permit the telescoping of two contiguous boxes and the entry of the guides on the one into the depressions on the other.

3. In a one-piece press-box for multiple presses, a main portion having a grating and parallel sides, said sides having integral sections of reduced thickness, and provided with flanges below, which afford inner opposing vertical faces, having a somewhat smaller distance from each other than the parallel sides of the main portion, said box having corner depressions above and projecting guides below, whereby two adjacent boxes are always kept in telescope with each other to prevent displacement of the mat, substantially as described.
